-=============================
-Aspeed AST2400 Pin Controller
-=============================
-
-Required properties for the AST2400:
-- compatible : 			Should be one of the following:
-				"aspeed,ast2400-pinctrl"
-				"aspeed,g4-pinctrl"
-
-The pin controller node should be the child of a syscon node with the required
-property:
-
-- compatible : 		Should be one of the following:
-			"aspeed,ast2400-scu", "syscon", "simple-mfd"
-			"aspeed,g4-scu", "syscon", "simple-mfd"
-
-Refer to the the bindings described in
-Documentation/devicetree/bindings/mfd/syscon.txt
-
-Subnode Format
-==============
-
-The required properties of pinmux child nodes are:
-- function: the mux function to select
-- groups  : the list of groups to select with this function
-
-Required properties of pinconf child nodes are:
-- groups: A list of groups to select (either this or "pins" must be
-          specified)
-- pins  : A list of ball names as strings, eg "D14" (either this or "groups"
-          must be specified)
-
-Optional properties of pinconf child nodes are:
-- bias-disable  : disable any pin bias
-- bias-pull-down: pull down the pin
-- drive-strength: sink or source at most X mA
-
-Definitions are as specified in
-Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt, with any
-further limitations as described above.
-
-For pinmux, each mux function has only one associated pin group. Each group is
-named by its function. The following values for the function and groups
-properties are supported:
-
